Differences in Physical Performance Between U-20 and Senior Top-Level Brazilian Futsal Players

The aim of this study was to compare performance in the Yo-Yo IR1, 20-m sprint, COD test, loaded and unloaded lower-limb muscle power tests (SJ, CMJ and jump squat (JS) tests), as well as resting and exercise HRV parameters in high-level senior professional and U-20 futsal playersMETHODS: All the players (18 senior and 15 U-20 male players) performed the Yo-Yo Intermittent Recovery Test level 1 (Yo-Yo IR1), 20-m sprint, COD test, loaded and unloaded lower-limb power tests (squat jump [SJ], countermovement jump [CMJ] and jump squat [JS] tests), as well as resting and post-exercise log-transformed root-meansquare difference of successive normal RR intervals (lnRMSSD) recording. The t test for independent samples and magnitude-based inference were used to compare the groups.
